Brainiac is a fictional character that appears in comic books
published by DC Comics. The character first appeared in Action
Comics #242 (July 1958), and was created by Otto Binder and Al
Plastino. An extraterrestrial android (in most incarnations),
Brainiac is a principal foe of Superman, and is responsible for
shrinking and stealing Kandor, the capital city of Superman's home
planet Krypton. Due to complex story lines involving time travel,
cloning, and revisions of DC's continuity, several variations of
Brainiac have appeared. Most incarnations of Brainiac depict him as
a green-skinned being in humanoid form. He is bald, except for a
set of diodes protruding from his skull.
In 2009, Brainiac was ranked as IGN's 17th Greatest Comic Book
Villain of All Time.
